Will Cashmere…

By | Uncategorized | No Comments

At Castanea we are aware of the daily struggles we are all going through. We are experiencing a rollercoaster of mixed emotions. Anxiety, denial however at the core we remain hopeful as we know our unsung heroes are out there doing their very best for us.

As you’re spending so much time at home we suggest it’s time to dig out your old cashmeres and bring them back to some new life. Cashmere is so comforting & if it’s only for a short period that’s what we need right now.

We though you would bring you our top 5 “Will Cashmere…”
and we hope this will shed some more light on the most frequently asked questions we get here at Castanea & help you bring new life to your cashmeres. 

1. Will Cashmere Shrink?
Yes it will, but only if washed improperly, heat is the main culprit, if cashmere encounters any hot water, it will shrink significantly! Always hand wash your cashmere in cold water with a mild detergent. Cashmere can also be dry cleaned but our personal favourite is a cold hand wash.

2. Will Cashmere keep me warm?
Yes. Oh my god yes. Cashmere is an amazing insulator, about three times as insulating as Sheep’s wool. However it does also depend on the ‘weight’ of the cashmere garment, heavier weights will be more appropriate for winter, while lighter weights can be used year around. Castanea offers up to 6ply (meaning 6 ends of yarn) cashmere for the winter months & 2ply for spring summer!

3. Will moths destroy my cashmere?
Moths are one of Cashmeres worst nightmares. These little critters love creating holes in your favourite cashmere clothes. They’re attracted to the protein in the cashmere fibers, as well as human oils! We recommend always keeping your cashmere washed and cleaned regularly & wrapped in tissue or breathable cotton bag in your wardrobe with some cedar balls.

4. Will cashmere stretch?
It shouldn’t, unless stored & washed improperly. To prevent stretching, Cashmere should never be hung & should be laid flat after washing & storing for the best longevity.

5. Will my cashmere fade?
Do not dry in direct sunlight as this will fade your beautiful sweater. Your cashmere should not fade otherwise and if it does, get a refund!

St Patrick’s Day and Irish Design

By | Cashmere Sweaters, Fashion, Luxury Sweaters | No Comments

Did you know the original colour of St Patrick’s Day was actually blue? The green colour is actually influenced by our American friends, who took on St Patrick’s day, and associated it with Ireland’s most common colour, Green! 

Here at Castanea, we believe in celebrating the new & the old.  

Through our quality and attention to detail, we honour everything Irish.

And in celebrating the old, we have the Janie sweater. Constructed from 100% Cashmere, a beautiful super-soft fitted sweater with tonal ribbed cuffs made in a beautifully soft Glaciar & Ocean blues. The front has simple perforated details with a time-honoured loose rolled hem finish. It’s easy, it’s unique & above all it’s comfortable.

By | Cashmere Sweaters, Fashion | No Comments

In our opinion every day should be Women’s day. However, we use the cards we are dealt, so this March 8th, remind yourself of your beautiful femininity by wrapping yourself in a truly luxurious piece of Castanea cashmere. We are delighted to introduce our  brand new Spring/Summer collection that is bound to have you feeling chic, casual, cool & the main thing feeling yourself this Women’s day. 

‘Mary’s Cashmere hoodie’ comes to mind.  Its named after Mary an avid bee keeper. Her hard-work and determination for quality define this piece, as we wanted to uphold these qualities and thus, the ‘Mary’s Cashmere hoodie’ was created. Its crafted in 100% Cashmere in a lightweight honeycomb knit structure, directly inspired by beehives. 

Its in a beautiful Estate blue, complimented with a soft-melange Glacier blue too. It’s a super soft relaxed fit hoodie, with a modern stripe up the side to give a side of modernity to a time honoured design.

Autumn winter 19 inspiration

By | Cashmere Sweaters, Fashion, Luxury Sweaters | No Comments


This is the Escaltura 2, 1977 – 2007 by Ascanio MMM.  We were immediately drawn to the modern linear twists & turns, therefore this lead to the design of one of our best sellers for the season. The Thapa sweater.

A season favourite at Castanea. The Thapa sweater was inspired by the Escultura 17, 1978-2003  sculpture by Ascânio MMM.  Brazilian artist Ascanio MMM is able to experiment with different angles and volumes to create unique sculptural geometric formations.

The Thapa slim hand knitted cashmere sweater has a basic body however the sleeve details make it come to life. The bracelet sleeves feature silk and cashmere knitted sculptural rectangles that fall to the wrists with a celebrated elegance.

Keep it tonal or go for a pop of colour for the more adventurous wearer.

A guide to Care for your cashmere

By | Cashmere Sweaters, Fashion | No Comments

To get the most from your Castanea cashmere regular cleaning is required. It is important to give them a thorough cleanse & avoid having a sleeping pile of knitted sweaters in your laundry room! Unfortunately there are harsh consequences to washing your cashmere incorrectly; so please follow this guide carefully. Cashmere does fall into the hand wash & dry clean only category. It can be washed in a laundry bag if your machine has a cold hand wash cycle but they will last much longer if washed by hand.

Step 1.

It is best to use a clean sink or basin, make sure there is no residue of cleaning products on the surface of whatever you choose. Fill the basin with cool to tepid water. It is not necessary to freeze your hand off with polar ice cold water! Add a small amount of gentle cashmere or knitwear detergent. We recommend the Laundress cashmere shampoo, Ecover delicate, or you can use Woolite. Briskly swirl the shampoo in the water with your hand for even distribution & to generate suds.

Step 2.

Turn your knit inside out and submerge in the water. Make sure to not mix any colours together.

Gently massage the soapy water through each fiber. Don’t rub, wring or twist the fabric while washing. Spot treat any problem areas with a squirt of neat detergent and massage gently with fingertips. Allow the garment to soak for 5 – 10 mins. It might be good to set a timer at this point as you may walk off and forget!

Step 3.

Drain the bowl or sink and rinse until the water runs clear. Be sure to use the same temperature water as you used to wash. Don’t wring or twist to remove excess water, instead lay the item out on a towel, gently roll up (like a sausage roll) and lightly press. Remove the sweater from the towel and reshape by hand. Lay the cashmere on a dry clean towel and let it air dry.

Button up cardigans and pull pockets straight. Keep it away from heat sources like radiators and sunlight, allowing it to air-dry naturally.

Step 4.

Once dry, fold your cashmere carefully. You can give it a gentle steam to remove any creases. Do not lay an iron flat on your cashmere. If you can, we recommend you wrap your cashmere in acid-free tissue paper, which preserves original colour and protects against damp and dust. Store your clothes in a well-aired area, dust free and covered, away from sunlight.


Moths love cashmere and they are particularly attracted to the natural oils we produce when wearing our cashmere. They love our dirty clothes so to keep the dreaded moths away we recommend hand washing your sweaters regularly. Also lining your chosen storage area with fragranced anti-moth paper. If it’s a wardrobe, invest in some cedar balls or scented sachets.


Cashmere is a fine fibre and pilling will happen depending on the amount of wear and tear you give it. This is not symptomatic of inferior quality, but rather an inevitable consequence of the careful processing of this fine fibre. Avoid any rubbing motions with your handbag & purses. Also try to keep your knits away from jewellery as it can cause snags.

Pilling can easily be removed using de-bobbling comb or even a standard razor, though you need to be very careful not to cut the fabric if doing so.

Your Castanea cashmere will improve with age if cared for properly, and will last for years to come.

Gifts for her

By | Cashmere Sweaters, Fashion | No Comments

Here at Castanea we think anything in cashmere makes a super special gift any woman won’t forget in a hurry. It really is a gift that keeps giving! The fiesta red coloured sweaters & accessories are the obvious choice for a truly festive & luxurious gift.


However if you want to splurge we recommend the Liza sweater. It is crafted from a super soft mid-weight knit with voluminous waffle puffed upper sleeves that lead into chunky ribbed cuffs, and features a high turtle neck & thick luxurious cardigan stitch body.

Get it in Fiesta Red for the social butterfly,  

Pale Blue for the modern woman,

or Chiffon Pink for the hopeful romantic!
